ESP32 Forum

Hey guys,

I am new here and I just thought about using the ESP32 as a WiFi dongle for my RaspberryPi. I just buyed a matrix voice board which has an integrated ESP32.

Is there a possibility to use the chip after boot up as a wifi dongle so I can see them in the ifconfig (in Linux).

Thanks to all who can help!
Best regards,
Robert

No, sorry, I don't think we have slave drivers for that at this moment.

I really want to do this as well. I know the standard answer appears to be use an ESP8089, but it does not support the 802.11 LR mode. I would like to use this on a ESP32 WROVER module with some directional sector antennas to cover an area of approximately 500 meters.

I was thinking about using the AT command firmware, and sending data from my Linux application to the ESP32 via UART, then crafting packets with AT and sending via WiFi, but that seems like a bit of a hack. It would be a much cleaner solution if I could just use the ESP32 as a WiFi interface via SDIO.

I was going to go through the eth2wifi code example and see if there is some way to implement it to get data off of a host MCU while using the ESP32 as a slave for WiFi but haven't gotten through it yet.

Any suggestions in this area would be very appreciated.

Would it be possible to emulate or otherwise achieve an ethernet connection between the ESP32 and a Raspi/Beaglebone/Linux SOC and just use the ESP32 as an IP router? Assuming the ESP32 manages the WiFi connection and and has a way to receive the IP packets all it would have to do is forward all packets received to the default gateway of the WiFi interface.

Have anyone did this? Is there any guide or blog that I can refer to implement this? I also want to use ESP32 as my Wifi dongle which I will use to connect to the Wifi AP.
